I have old drivers from 2011 and want to update them
But can I safely remove them, eg system driver:
Intel(R) 6 Series/C200 Series Chipset Family PCI Express Root Port 1 - 1C10
and many others like it?
I've first removed network adapter driver which was also from 2011 and update that succesfully to latest version.
Now only the chipset, which installs fine on its own but through the update utlity it fails.
You do not need to upgrade drivers for PCI roots, cause such devices are managed by Windows core drivers itself, Intel utility just named it correctly (from, like "Generic PCIE Root hub"). Once the naming was done, no need to do anything more with such devices (actually, nothing will be done).
